Description
I have Saga 2.2.6 installed with QGIS 2.14.1 on linux.
Since Saga version 2.2.4 the name of the parameter "INTERPOL" changed to "RESAMPLING" in "io_gdal 0".
This is called by nearly all raster tools of the qgis saga geoalgorithms.
I could bypass the problem by adding a
SagaAlgorithm224.py (copy the SagaAlgorithm214.py)
,changing line 64 from
return 'io_gdal 0 -TRANSFORM 1 -INTERPOL 0 ...
to
return 'io_gdal 0 -TRANSFORM 1 -RESAMPLING 0 ...
,and adding the SagaAlgorithm224 Class to the SagaAlgorithmProvider.py module as Supported version
and creating a symlink from the description folder 2.2.3 to 2.2.4, 2.2.5 and 2.2.6 in the /usr/share/qgis/python/plugins/processing/algs/saga/description folder
(knowing that the Descriptions then points to the wrong version).
Is a support for saga 2.2.4 or newer versions in qgis planned?

This known issue with SAGA. SAGA devs break API in every minor version making maintenance really hard.

Just leaving my temporary way to solve this (for reference). In SagaAlgorithm214.py:
from SagaUtils import getSagaInstalledVersion
...
if getSagaInstalledVersion() >= "2.2.4":
return 'io_gdal 0 -TRANSFORM 1 -RESAMPLING 0 -GRIDS "' + destFilename + '" -FILES "' + source + '"'
else:
return 'io_gdal 0 -TRANSFORM 1 -INTERPOL 0 -GRIDS "' + destFilename + '" -FILES "' + source + '"'

RESAMPLING is already the default, so it can be removed safely

In QGIS 3, the temporary solution is similar. In SagaAlgorithm214.py:
from .SagaUtils import getInstalledVersion
...
if getInstalledVersion() >= "2.2.4":
return 'io_gdal 0 -TRANSFORM 1 -RESAMPLING 0 -GRIDS "' + destFilename + '" -FILES "' + source + '"'
else:
return 'io_gdal 0 -TRANSFORM 1 -INTERPOL 0 -GRIDS "' + destFilename + '" -FILES "' + source + '"'
